Rolex Tudor ETA 2484 Servicing


Recommended Posts

I am servicing a vintage Rolex Tudor for a friend. It has an ETA 2484 movement. I, of course am very nervous doing this as I typically do pocket watches as you know. Do you have any manuals on the breakdown of this watch? As well, are there any tricks I should know while disassembling or assembling. Very scary as this is a $3500 watch and I really don’t want to Frig it up.

 

Thanks, Cheers

Hi there I don't have a manual but I am certain that movement is based on an eta 2452 and if you have a screwed hairspring I have some  spare coming, let me know If you need oiling recommendations, use the technical sheet for the 2824-2....

Could you provide the link for the technical sheet. And big thanks.

As @Graziano mentioned that he thought the movement was based on the ETA 2452, I thought you might find this post (ETA 2472 - Disassembling the automatic device) of mine useful. Also, if the date complication is similar to that of the ETA 2472 you might also find this post useful (ETA 2472 - Disassembling the date mechanism).

Also, if this movement has a setting lever screw similar to the setting lever screw of an ETA 2472 that I serviced somewhat recently, it is extremely important to replace the setting lever screw before the barrel bridge is replaced. This is trickier than you might think as the setting lever screw can be replaced after the barrel bridge has been replaced but will lead to several problems that can be hard to foresee. You can read more about my ordeal with the setting lever screw here and here.

So, if you your movement indeed is similar to my ETA 2472 you'll find my complete service walkthrough of it here including my lubrication suggestions based on ETA's technical communication for the 2824-2 as suggested by Graziano. The walkthrough consists of about 130 disassembly pictures and about 130 assembly pictures.

Good luck!

That's a great walkthrough :thumbsu:

Maybe this thread will help?

Hardly, as it's the duplicate of this one.

jdrichard, please do not post duplicate topics, and post in the proper section. Otherwise it just makes difficult to help you.

That is strange. You just turn the dial until the date sets.

Very common in older Wristwatch movements with date complications. It just requires the tedious practise of cranking forwards. A lot of people who wear watches in rotation tend to skip date setting on such watches.

Quick set requires a separate cam which engages the date wheel teeth on the first pull out point to facilitate the rapid advance so it'll be very evident when you strip the dial side as it'll be connected to the keyless works where the date advance is usually over by the 9/10 on the dial position driven by the hour wheel.

Date changes as hands advance past hr24. At this point turn hands anticlock to hr8 then forward past hr24, this will change the date. 

 

Just be a bit careful if the cannon pinion sits so hard on the center wheel that it rotates train wheels in the wrong/opposite direction making the seconds hand move anti-clockwise. There's a video on the YouTube Watch Repair Channel about this. I'll see if I can find it a bit later.

Oh BTW, well done! :Bravo:

Thank you. Returned to owner and He is very satisfied: owns an antique store in Winnipeg Canada.

    • Hi Fernando, read carefully what @eccentric59 wrote, it is the key to You problem. Lubricate the cannon pinion. Take care to understand what is it's function. When You set time, the train doesn't move, but only the cannon pinion moves. Put hte lever back in it's place, it has nothing to do with time setting
    • Hi fernando. Let us know how you get on.
    • OK, in You case You will assemble the movement with the line attached to the barrel and fusee and will  wind the line  entirely on the barrel after that. It is important when replacing the line to know the correct lenght of the line. The rule is that when line wound on the fudsee entirely, about 1/4 turn still to remain on the barrel. Yes, no tension. The ratchet is not placed yet, the spring in the barrel is complitelly unwound. At the end of the step the fusee is empty and the line is attached to it and strained perpendiculary to it, not on tangent. The escape wheel. Use whatever that will not damage anything. Yes, this is typing mistake, sorry. The word 'pendulum' here is not correct, You should use 'anchor' and yes, it is removed from the movement at this point, according my instruction 1 (Ihave used the word 'lever' there):   Ok, let sey the barrel arbour makes 6 full turns when winding the spring in the barrel from unwound to fully wound state of the spring. Let sey that the barrel makes 4.5 full turns when winding the clock from fully unwound (the line is on the barrel) to fully wound (the line is on the fusee) state. This means that You should not wind the spring in the barlel when adjusting the initial tension to more than 1.5 turns of the arbour of the barrel.  If You make 2 full turns, then when winding the clock, the barrel will be able to turn to only 4 turns, so the limiting device will not limit the rotation of the fusee arbour and You will be able to force the line much more than when the limiting device acts, also the power reserve will be less. Hope this is clear now... Yes, but again - not the pendulum, but the anchour.   About the loosing time... In this kind of escapement, the frequency pritty much depends on the torque. The higher torque - the highrer frequency. This is because this escapement forces the pendulum to oscillate significantly faster than it's own resonant fequency. The frequency depends on the 'depth' of the escapement too - the deeper escapement is, the lower the frequency, and the higher amplitude of pendulum oscillations. The heavier the pendulum is, the harder to the movement (the escapement torque) to force the pendulum to oscillate faster than it's own frequency. And in the end, the own pendulum frequency depends only on the pendulum lenght and a little on the suspension spring 'strenght' This are all the relations between all the factors. You can try to use the old spring (if it is not broken) and see if the clock will work faster with it. Yes, the old springs of fusee clocks sometimes give bigger torque than modern ones, no matter if they seem to be 'set' You can shorten the pendulum to achieve correct frequency. If the torque is reduced, but enough for the movement to work reliably,  then reduced torque will only lead to lessen the wear. The torque in fusee movements is more or less constant all the time, this is the function of the fusee. You can use the Clock Tuner  free app for android to adjust faster the clock rate. You will need to know the BPH of the movement, so count the teeth of the wheels and pinions and calculate the BPH
    • Hi! My bad. I meant to say that when the pallet fork is installed I cant move the wheels "using the crown in the setting position" Really in truly my number 3 was redundant and badly written (trying to explain myself went all wrong). I dismantling partially the watch (calendar, remontoir, Balance and Pallet fork). I think I would need to go that way...  Thanks for your comments...    
    • this is what happens if you don't fully do all of your research. I found the safe answer I found your exact caliber we got a mainspring number we got a price at a decent price for the original spring verified that the spring number at least on bestfit agrees with what we have so it was safe yes I did look in the GR catalog I had seen that 200 watch has a spring similar to what you perceive it should be. But to be honest I never looked at the 200 watch to see what its mainspring was. then the other amusement I went back to the bestfit online because if the 200 have the same spring I were to see that when I snipped out the image up above. Turns out they don't even show a 200 listing at all.
